Abstract: At the time before damming the river Danube in the area between Regensburg and Geisling, because of the pollution the prevailing macrozoobenthic community could not be characterized as a natural or near-natural potamal community. At that time generalists dominated and only a few stenoecious species of running water had a small share in the species spectrum. In the first year after the filling of the impoundment Geisling (1986) a massive appearance of chironomid populations occured. The analysis of the catches proved an outbreak of two chironomid species: the Chironomus-plumosus-group and Glyptotendipes paripes. In unusually high densities the sphere shell Sphaerium corneum and the crustacean Corophium curvispinum were found, too. Until today the productivity of the impoundment Geisling has still remained high. But it seems now that the community begins to stabilize.Keywords:
